Again please, don't add deprecated code. avctx->coded_frame is not meant
to be used in new modules, and is present in old modules only until
removal for backwards compatibility.

Nice, glad to see this was implemented.
If no one else is against it I'm fine keeping the #else case for the
time being even if it may flag intra frames as inter in the encoder
stats since i plan on bumping the minimum required version as soon as a
new libaom release is tagged. A lot of development has taken place and
plenty of API was added that makes 1.0.0 unoptimal.

Nit: You can reduce duplication by removing the two lines below and
moving the #else one line up.
